While I can see the theoretical aspect of that, how would a
practical implementation look like?  Say, I've got a PWM base
frequency of 10 kHz, and a modulation spectrum ranging from
9.5 to 10.5 kHz (so the bandwidth is 1 kHz), how would I
design the filter to extract my modulation signal?

Never trust an operating system you don't have sources for. ;-)
